WALTER I-I. PERKINS, OF'WATERTOWN, NEW YORK, ASSIGNOR T0 JAMES B,WISFQVOF WATERTQWN, NEW YORK.

1,025,642. Original application filed September 9,

To all whom t may concern:

Be it known that I, qWALTER H. Primi-ins,

` a citizen of the United States, residing at Vatei-tow'n, in the countyof Jefferson and State of New York, have invented certain new and usefulImprovements ,in Ls, of which the following is a specification.

This invention relates to improvements in Ls, designed for use inconnection with various sanitary appliances, and the invention relatesparticularly to Ls for receiving the waste and ovenow from bath-tubs,

sinks and the like.

The features and parts ofntlie invehtibii will be understood from thedetailed def 'thelike, consisted of two or more parts,

which were made separately and then fastened together by various meansfor making up the'complete devices. To make, assemble and linish theseveral parts under the older styles of over-flow Ls requiresconsiderable time, labor and material, which necessarily increases thecost of the production of the said devices, and besides most of the saidfittings are Vmore or less complicated and.

clumsy.

It is an object of the present invention to provide over-flow Ls for usein connection with bath and sink xtures, wherein4 the L consists of buta single part, which is;

formed up by means of suitable dies and tools, whereby 1 am able to'produce Ls of f the class, which are lighter', stronger and simpler, andwhich can be made at smaller cost, than any of the older devices knownto me.

In the drawing, 2 represents the body or sheil of the L, which ispreferably made in one part, from a plain piece of sheet metal, which ispressed and rolled and formed into I Speeication o f'LettersPatent.

al hollow body, having a smooth exterior and interior, as shown.

3 represents an integral iiange which sur-, rounds and over-hangs abroad flaring mouth 4. The flange 3 may be dished or recessed, as shownin Figs. 1 and 2, to receive a packing (not shown), or the said flangemay be made plain and flat.

5 represents a laterally arranged tubular neck, which is preferablyformed by dra-wv v Patented May 7, 1912. t v 1911Seria1 No. 645,439.Divided and this application filed' January 2, 1912. `Serial No.668,999.

ing out the metal at right angles to the axis ot' the body 2, to which awaste or'ot-her pipe may be attached 4in. any suitable manner. Thebottom or back of the neck-5 is preferlably disposed in the same planeas the bottom or back of the body 2, for effecting complete draining andself-cleaning of the fitting.

To adapt my improved L for use in con-` nection with the over-flow ofbath-tubs and sinks, I provide, by means of spinning or rolling, a plainland comparatively narrow c `iiresponding bead or rib 13 around theinner surface of the body, just back of, and concentric to the liaiige 3ot the L. The overf fiow L is generally attached to thev vessel by meansof a bolt 14 which pierces a strainer 15, then passes through a hole inthe wall of the vessel 6, and is screwed into a bridge 16, which isdisposed diametrically across the interior of the body of the L.' .Thebridge 16 has a length equal to the largest diameter of the body of theL, and is preferably disposed behind tl'ie rib 13, which serves as astop, for preventing the bridge from being accidentally displaced orpulled out through 'the mouth of the L, when the bolt 14 is screwed into clamp the parts to the vessel.

AAfter the bridge is`placed in position', its

opposite ends areusually soldered to the walls of the body 2. By theprovision of the inwardly facing rib 13, the bridge 16 may be made outof narrow strip of sheet metal, which may be i'eadily'and securelyapplied to the L.

Under my improved construction and arrangement, the body of the L may bemade of lighter gage of metal, and yet have the .same or even greaterstrength, than where two or more separate-parts are joined together.Aside from the feature of constructing the L ,in one part, a peculiarly75 semi-circular groove 12, which produces a l novel and valuablefeature of the L of the present invention consists in providing theintegral rib 13, which affords, novel, simple and eective means forconnecting the securing devices or parts directly to the body of the L.

-This application is filed as a division of' my application ledSeptember 9, 1911, Serial Number648139.

Having described my invention and set forth its merits what I claim isl. A wrought metal L, comprising a holloW body having a Haring mouthsurrounded by a dished flange, and having the metal of the body adjacentthe said flange depressed inwardly to form a Conca-vo-convex rib, thesaid rib encircling the interior of the body and having a lessdiameter-than the said mouth and adapted to prevent the accidentalwithdrawal of part-s connected to said body.

2. An L, comprising a Wrought metal body, having a circular mouth and alaterally drawn tubular neck and a part of the metal of the body betweenthe said mouth and the said neck depressed inwardly to form an internalannular rib, and a bridge capable of being disposed diametrically 1n thesaid body and to be held from displacement by said rib.

I n testimonyyvhereof I affix my signature in presence of two Witnesses.
